The last version of Android (8.0) introduced a new function which is causing issues when the Tahuna app is in the background. This may lead to the app closing and your E-Bike/sensor connection being dropped (Bluetooth turned off) or the loss of data, eg. an ongoing recording or navigation.

To prevent this from happening, you can enter the settings menu of your phone, find the battery management section and turn off battery optimization for the Tahuna app.

The method varies from phone to phone as different manufacturers have different menu arrangements – we will try to cover the most popular systems below:

Nexus/Pixel phones:

Open ‘Settings’

Select ‘Apps & Notifications’

Tap ‘See all apps’

Select ‘Tahuna’

Tap ‘Battery’

Tap ‘Battery optimisation’

Open the drop-down menu with the arrow and select ‘All apps’

Tap ‘Tahuna’, select ‘Don’t optimise’ and tap ‘Done’

Samsung Galaxy S8:

Open ‘Settings’

Select ‘Device maintenance’

Tap ‘Battery’

Tap ‘Battery usage’

Open the drop-down menu (triple dot button at the top right)

Select ‘Optimise battery usage’

Set the list to ‘All apps’ at the top of the screen

Look for ‘Tahuna’ and turn on the toggle switch

Huawei phones:

Open ‘Settings’

Select ‘Battery’

Tap ‘Launch’

Look for ‘Tahuna’ and turn off the toggle switch

This will open up a menu with further options: make sure that the ‘Run in background’ option is turned on

Simply log in to your preferred service and download the desired routes in GPX format. Save these to your phone’s storage and proceed to open the Tahuna App.

– Tap the ‘Memory’ button in the Main Menu, select the ‘Imported’ tab (swipe to the right) and tap the “Down arrow” button at the top right of the screen.

– You can either look for the GPX file manually (‘Browse’), or you could just select ‘Auto search’ and let the App locate it for you. The imported route will be visible under the ‘Imported trips’ category of the ‘Imported’ tab.

Option 4: Associating .GPX file type to the Tahuna app

Associate GPX files with the Tahuna App: using your preferred file manager, locate the desired GPX file and open it. The system will prompt you with the option of choosing the default application associated to the file type: set Tahuna as the default application.

– Record/create a new tour on your phone and save it.– Locate the tour you would like to transfer (‘Memory/My Stuff’).– Open it and access the ‘Further options’ menu at the top right of the screen.– Tap the ‘Share’ option and select ‘Link’.

This will upload the tour to the TAHUNA Sharing Site, making it visible within the TAHUNA Tool. You can then transfer it from the Tool’s ‘Online’ pane to the desired device (if it is connected).

TAHUNA needs permissions in order to perform certain tasks. These include the location (to locate you on the map), Bluetooth (in order to connect to sensors), the camera/gallery (to attach pictures to your tours) and storage (to look up/manage GPX and TGPZ files).

If you have a Teasi Core, you will notice that it asks for permissions upon pairing. These are access permissions to your contacts and messages and they are only needed so we can display notifications about incoming calls/messages on the Teasi Core’s screen.
